[Haskell] problem with hs-plugins 1.1 on Windows: _WaitForSingleObject

I compiled a fresh darcs-get of the latest hs-plugins (through patch 209). it all compiles fine, but the tests die with complaints like this one: +Main.exe: +c:/ghc/ghc-6.8.1.20071102/lib\base-3.0.0.0/HSbase-3.0.0.0.o: unknown symbol `_WaitForSingleObject' +Main.exe: user error (resolvedObjs failed.) + Other unknown symbols: directory-1.0.0.0/HSdirectory-1.0.0.0.o: unknown symbol `_GetTempPathA' process-1.0.0.0/HSprocess-1.0.0.0.o: unknown symbol `_CloseHandle' One other error: +Main.exe: unloadObj: can't find `c:/ghc/ghc-6.8.1.20071102/lib\old- locale-1.0.0.0/HSold-locale-1.0.0.0.o' to unload +Main.exe: user error (unloadObj: failed) Any suggestions?
